Apricot Glazed Pork Kabobs

Stir together preserves, liqueur and butter, simmer in a small saucepan until butter is melted. (OR combine ingredients in a 2-cup glass measure; microwave on High 1 minute). Place pork cubes in heavy plastic bag, pour 3/4 cup apricot mixture over to coat. Marinate at least 30 minutes. Thread pork onto 4-6 skewers, grill over hot coals 10-12 minutes, turning occasionally and basting with marinade. Heat remaining apricot sauce to boiling and serve alongside kabobs, if desired.
